According to a government agency, the average workweek for an adult in October 2018 was 32.5 hours. Assume the population standard deviation for the number of hours worked per week is 6.0 hours. A random sample of 35 adults worked an average of 33.7 hours last week. a. Do the results from this sample support the claim by the government agency? b. Identify the symmetrical interval that includes 84% of the sample means if the true population mean is 32.5 hours per week. a. Do the results from this sample support the claim by the government agency? Consider a probability of less than 0.05 to be small. The probability that the sample mean will be greater than 33.7 hours is 0.05. (Type an integer or decimal rounded to four decimal places as needed.) The result support the claim by the government agency that the mean is 32.5 hours because this probability is

According to one study, brain weights of men are normally distributed with a mean of 1.10 kg and a standard deviation of 0.12 kg. Use the data to answer parts (a) through (e). Click here to view page 1 of the table of areas under the standard normal curve. Click here to view page 2 of the table of areas under the standard normal curve. a. Determine the sampling distribution of the sample mean for samples of size 3. Interpret your answer in terms of the distribution of all possible sample mean brain weights for samples of three men.
